What happened: I have been following this guidelines: https://kubernetes.io/docs/setup/minikube/ and I have the "connection refused" issue when trying to curl the application. Here are the steps I did
~~> minikube status
minikube: Stopped
cluster:
kubectl:
~~> minikube start
Starting local Kubernetes v1.10.0 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
Loading cached images from config file.
~~> kubectl run hello-minikube --image=k8s.gcr.io/echoserver:1.10 --port=9500
deployment.apps/hello-minikube created
~~> kubectl expose deployment hello-minikube --type=NodePort
service/hello-minikube exposed
~~> kubectl get pod
NAME READY STATUS RESTARTS AGE
hello-minikube-79577c5997-24gt8 1/1 Running 0 39s
~~> curl $(minikube service hello-minikube --url)
curl: (7) Failed to connect to 192.168.99.100 port 31779: Connection refused
What I expect to happen: When I curl the pod, it should give a proper reply (like in the quickstart: https://kubernetes.io/docs/setup/minikube/)

Create a new Pod that runs curl To do that, I use the kubectl run command, which creates a single Pod. Kubernetes will now pull the curlimages/curl image, start the Pod, and drop you into a terminal session. So now you can use curl! Make sure you run curl in the same Kubernetes namespace which you want to debug.
Create a Service. By default, the Pod is only accessible by its internal IP address within the Kubernetes cluster. To make the hello-node Container accessible from outside the Kubernetes virtual network, you have to expose the Pod as a Kubernetes Service.
Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node. Minikube is available for Linux, macOS, and Windows systems.
You can use the kubectl command to deploy a test application to your Minikube cluster.
Not sure where you got the port 9500 from but that's the reason it doesn't work. NGINX serves on port 8080. This should work (it does for me, at least):
$ kubectl expose deployment hello-minikube \
--type=NodePort \
--port=8080 --target-port=8080
$ curl $(minikube service hello-minikube --url)
